Patients with a CMR in keeping with myocarditis were trending to be younger (40 (24–52) years vs. 44 (30–58) years; p = 0.074), were more often male (86 (76%) vs. 27 (24%); p < 0.001), had higher circulating inflammatory markers at presentation (e.g., c reactive protein 21 (4–67) mg/L vs. 3 (1–21) mg/L; p < 0.001) and more frequently had elevated circulating troponin levels (103 (96%) vs. 35 (76%); p < 0.001) than patients with normal CMR findings. This evidence concerns the gene CRP and myocarditis.
